1.爬取博客园的所有随笔的url以及计数,还有对应标题

import re
import requests
from lxml.html import etree
import json

#对于链接和标题的一个整合
def func_1_deco(func_1):
    def wrapper(*args,**kwargs):
        dic = dict()
        lis = func_1(*args,**kwargs)
        count = lis[0]
        url_lis = lis[1]
        dic['count'] = count
        name_xpath = '//*[@id="cb_post_title_url"]/text()'
        for url in url_lis:
            response = requests.get(url)
            response = response.text
            response_html = etree.HTML(response)
            name = response_html.xpath(name_xpath)[0]
            print(name)
            dic[name] = url
        return dic
    return wrapper

@func_1_deco
def func(url):
    lis = []
    count = 1
    while True:
        count_1 = len(lis)
        response = requests.get(f'{url}default.html?page={count}')
        response = response.text
        data_1 = re.findall(' href="(.*?)"', response, re.S)
        for a in data_1:  # type:str
            if a.startswith('http'):
                if a.endswith('html'):
                    if 'archive' not in a:
                        lis.append(a)
        count +=1
        lis = set(lis)
        lis = list(lis)
        count_2 = len(lis)

        if count_1 == count_2:
            return count_2,lis  #博客的数据量,博客里面随笔的url

        
dic = func('你的博客的首页地址') #注意结尾要有/,字典格式是有一栏'count'计数,其他均为标题+对应的url
